Stereoselective synthesis of 22-oxacalcitriol (OCT) and analogues modified at C25
摘要:
The stereoselective synthesis of 22-oxacalcitriol (OCT) has been achieved. The triene system was introduced using the Lythgoe-Hoffmann La Roche convergent Wittig-Horner approach to couple ketoester 7 with A ring phosphine oxide 8. The value of the resulting ester 6 for synthesis of C25-modified OCT analogues is exemplified by the synthesis or 5. (C) 2002 Published by Elsevier Science Ltd.
